Removing metadata from a record

All Crossref metadata may be updated by re-supplying your metadata record with changes included. A metadata record may not be fully deleted but you may need to remove certain types of non-bibliographic metadata from a record. This may be necessary if metadata was submitted by mistake, or when content migrates from one member to another. Some metadata provided for text and data mining or Similarity Check are publisher-specific and must be updated or removed when content is acquired by another member.

When a record is updated with bibliographic metadata, registered non-bibliographic metadata is retained as part of the metadata record unless we are explicitly instructed to remove it. Metadata that needs to be explicitly deleted includes:

This metadata may be deleted by supplying an empty parent element as per the examples below, and may be included in a metadata update or submitted as a resource deposit. Note that metadata submitted as part of a Crossmark update needs to be removed within Crossmark metadata as per the examples below.

Remove all Crossmark data

Remove all Crossmark data from a record by supplying an empty Crossmark element in a metadata deposit:

Funding, license, and clinical trial data may all be supplied as part of a Crossmark update. If you need to remove funding, license, or clinical trail metadata from your Crossmark metadata, you must submit the appropriate empty element within a Crossmark update. Note the other Crossmark metadata must be present as well to be retained.
